This study aimed to determine the prevalence of antibodies against Leptospira spp. and their regional distribution, and evaluate the main risk factors associated to the disease in cattle in the State of Goias, Brazil. The study was carried out using 4571 samples taken from 715 properties of 213 municipalities in the state of Goias. The samples were analysed by the microagglutination test (MAT). 62.2% of the samples were positive for at least one of the 16 serovars tested, with major prevalence of co-agglutination (40.24%), followed by serovars wolffi (14.53%), hardjo (12.70 %), grippotyphosa (10.55%) and shermani (6.55%). The prevalence of anti-Leptospira spp. antibodies was associated to the following factors: stratum of production, with a greater prevalence in stractumof beef cattle production; practice of artificial insemination; cattle breed; presence of sheep and goats; presence of capybaras; purchase of reproducers in exhibitions and from other properties; pasture rent at any time of year; presence of maternity paddock, and occurrence of abortions. It was concluded that leptospiral infection is endemic in Goias State.
